C-O'TTON AND WOOLl-ZN PAPER-MAKERS DRYING-FELT.

Application filed May 6, 1886.

To all whom it may concern,-

Be it known that 1, JAMES KENYON, a subject of the Queen of GreatBritain and Ireland, residing at Bury, in the county of Lancaster,England, have invented a new and useful Improveuient in Cotton andWoolen Paper-Makers Drying-Felts, of which .the following is aspecification.

The object of this invention is to so improve the cotton or woolendrying-felts used by paper-makers that the steam or vapo'r'which isgiven off from the paper during the drying process and in passing overthe drying-cylinders shall obtain a more ready escape than heretofore.This I effect by perforating the drying-felt with series of holesperpendicular to its top, and I perpetuate such free escape byprotecting said holes by metallic eyelets or their equivalent, ashereinafter set forth.

A sheet of drawings'acoompanies this specification as part thereof.

Figures 1, 2, and 3 of these drawings are face views offragments ofperforated dryingfelts, showing the same, respectively, with their holesprotected by eyelets, protected by stitching or binding, andunprotected. Fig.

1 represents a section on the'line x m, Fig. 11

Like letters of reference indicate corresponding parts in the severalfigures.

I take an ordinary cotton or woolen dryingfelt, F or F or F and providethe same with series of ventilating-holes h, perpendicular toSPECIFICATION forming part of Letters Patent No. 355,766, dated January11, 1887.

Serial No. 201,341. (No model) its top, sufficjent'tofacilitate theescape of the steam or vapor which emanates from the paper during thedrying process and in passing over the dryingcylinders. These holes orperforations I form by punching; butthey may be otherwise produced. Topreserve the ventilating-channels therethrough, and to prevent frayingfrom the edges of the punched holes, I provide each hole with a metalliceyelet, 6, Figs. 1, 1, to protect the same; or I stitch or with holesperpendicular to its'top and provided with eyelets or the like toprotect the perforations, substantially as herein specified. Intestimony whereof I affix my signature in presence of two witnesses.
